In this paper, we examine the problems facing a policy maker who observes inconsistent choices made by agents who are boundedly rational. We contrast a model-less and a model-based approach to welfare economics. We make the case for the model-based approach and examine its advantages as well as some problematic issues associated with it.

Much business ethics and corporate social responsibility literature suggests, implicitly or explicitly, that firms ought to engage in activities that can be characterized as philanthropy, namely, expending resources beyond what is required by law and market norms to promote others’ welfare at the expense of firm profits. However, this literature has struggled to provide a normative framework for evaluating corporate philanthropy, although scholars have noted that such expenditures can potentially remedy market failures and provide public goods more efficiently. I (...) articulate two specific rationales that can justify corporate philanthropy based on considerations of welfare economics: 1) firms making strategic but high-risk investments in activities that are likely to generate positive externalities even if they prove unprofitable and 2) firms possessing a strong comparative advantage in their ability to address a social problem at lower social cost. Moreover, these rationales can be evaluated by a concept I develop called the philanthropy multiplier, indicating the ratio of net positive externalities to net costs. I suggest that firms consider publicizing their philanthropy multipliers, and I discuss theoretical and practical implications. (shrink)

Intuition suggests there is no value in adding people to the population if it brings no benefits to people already living: creating people is morally neutral in itself. This paper examines the difficulties of incorporating this intuition into a coherent theory of the value of population. It takes three existing theories within welfare economics - average utilitarianism, relativist utilitarianism, and critical-level utilitarianism - and considers whether they can satisfactorily accommodate the intuition that creating people is neutral.

Hausman and McPherson provide an evidential defense of welfare economics, arguing that preferences are not constitutive of welfare but nevertheless provide the best evidence for what promotes welfare. Behavioral economics identifies several ways in which some people's preferences exhibit anomalies that are incoherent or inconsistent with rational choice theory. I argue that the existence of these behavioral anomalies calls into question the evidential defense of welfare economics. The evidential defense does not justify preference (...) purification, or eliminating behavioral anomalies before conducting welfare analysis. But without doing so, the evidential defense yields implausible welfare implications. I discuss how the evidential defense could be modified to accommodate behavioral anomalies. (shrink)

Although the economic thought of Marshall and Pigou was united by ethical positions broadly considered utilitarian, differences in their intellectual milieu led to degrees of difference between their respective philosophical visions. This change in milieu includes the influence of the little understood period of transition from the early idealist period in Great Britain, which provided the context to Marshall’s intellectual formation, and the late British Idealist period, which provided the context to Pigou’s intellectual formation. During this latter period, the pervading (...) Hegelianism and influences of naturalism arising from the ideas of Charles Darwin and Herbert Spencer were challenged by Hermann Lotze, a key transitional thinker influencing the Neo-Kantian movement, who recognised significant limits of naturalism, on the one hand, and the metaphysical tenor of absolute idealism, on the other, and attempted to provide a balance between the two. The goal of this paper is to make the provisional case for the argument that Pigou’s views on ethics were not only directly influenced by utilitarian thinkers like Mill and Sidgwick, but they were also indirectly influenced by Hermann Lotze, via the influence of the Neo- Kantian movement on late British idealism. To that end, Pigou’s essays in The Trouble with Theism (1908), including his sympathetic consideration of the ethics of Friedrich Nietzsche, reflect the influence of Lotze indirectly through the impact at Cambridge of: James Ward’s critique of associationist psychology, and consideration of the limits of naturalism including the critique of evolutionary ethics; Bertrand Russell’s rejection of neo-Hegelianism and, together with Alfred North Whitehead, the development of Logicism; and G.E. Moore’s critique of utilitarian ethics on the basis of the naturalistic fallacy and the development of his own intuitionist system of ethics. (shrink)

Hausman and McPherson defend welfare economics by claiming that even if welfare does not consist in preference satisfaction, preferences still provide good, if fallible, evidence of welfare. I argue that this strategy does not yet fully solve the problems for welfare economics stemming from the preference satisfaction theory of welfare. More work is needed to show that our self-interested preferences are sufficiently reliable, or in some other sense our best, evidence of well-being. Thus, (...) my aim is to identify the challenges that remain and clarify what additional work is needed before Hausman and McPherson's defence of welfare economics succeeds. (shrink)

This article examines Sagoff's criticisms of 'Four Dogmas of Environmental Economies' and argues that none of them are fatal. Many of the criticisms appear to rest on general misunderstandings about welfare economics. One misunderstanding is that transaction costs are theoretically indistinguishable from regular production costs. The theoretical distinction is that transaction costs vary under alternative policies and institutions whereas production costs are fixed by tastes, technology and endowments. Another misunderstanding is that market failure concerns only Pareto efficiency. Market (...) failure also concerns social efficiency with respect to the 'social welfare function', a device for making explicit ethical judgments about the interpersonal distribution of welfare. A third misunderstanding is that the 'rationality assumption' drives economic theory. In fact, the explanatory power of economic models comes mainly from explicit assumptions about the constraints facing economic agents. A fourth misunderstanding is that welfare economics is used as a mechanism for making legal and political decisions. Rather, welfare economics is used as a method for informing legal and political decisions by evaluating their outcomes on the basis of individual welfare. Used properly, it can improve the democratic process by bringing hidden costs and difficult issues to the attention of both policy-makers and the wider public. (shrink)

The tenuous claims of cost-benefit analysis to guide policy so as to promote welfare turn on measuring welfare by preference satisfaction and taking willingness-to-pay to indicate preferences. Yet it is obvious that people's preferences are not always self-interested and that false beliefs may lead people to prefer what is worse for them even when people are self-interested. So welfare is not preference satisfaction, and hence it appears that cost-benefit analysis and welfare economics in general rely (...) on a mistaken theory of well-being. This essay explores the difficulties, criticizes standard defences of welfare economics, and then offers a new partial defence that maintains that welfare economics is independent of any philosophical theory of well-being. Welfare economics requires nothing more than anevidentialconnection between preference and welfare: in circumstances in which people are concerned with their own interests and reasonably good judges of what will serve their interests, their preferences will be reliable indicators of what is good for them.

When one wishes to formulate, evaluate and implement public policies, the existence of a plurality of social actors, with interest in the policy being assessed, generates a conflictual situation. How such a conflict should be dealt with? This paper defends the thesis articulated in the following points: Different metrics are linked to different objectives and values. To use only one measurement unit for incorporating a plurality of dimensions, objectives and values, implies reductionism necessarily. Point can be proven as a matter (...) of formal logic by drawing on the work of Geach about moral philosophy. This theoretical demonstration is an original contribution of this article. Moreover, here the distinction between predicative and attributive adjectives is formalised and definitions are provided. Predicative adjectives are further distinguished into the new categories of absolute and relative ones. The new concepts of set commensurabi... (shrink)

This essay criticizes the proposal recently defended by a number of prominent economists that welfare economics be redirected away from the satisfaction of people's preferences and toward making people happy instead. Although information about happiness may sometimes be of use, the notion of happiness is sufficiently ambiguous and the objections to identifying welfare with happiness are sufficiently serious that welfare economists are better off using preference satisfaction as a measure of welfare. The essay also examines (...) and criticizes the position associated with Daniel Kahneman and a number of co-authors that takes welfare to be ‘objective happiness’ – that is, the sum of momentary pleasures.

With the collapse of the centrally controlled economies and the authoritarian governments of Eastern Europe and the former Soviet republics, political leaders are, with appreciable public support, espousing “liberal” economic and political transformations—the reinstitution of markets, the securing of civil and political rights, and the establishment of representative governments. But those supporting reform have many aims, and the liberalism to which they look for political guidance is not an unambiguous doctrine.

Multiple selves is a conventional assumption in behavioural welfare economics for modelling intrapersonal well-being. Yet an important question is which self has normative authority over others. In this paper, we advance an argument for what we call the ‘ontological approach’ to personal identity in behavioural welfare economics. According to this approach, ethical questions – such as which preference should be granted normative authority over another – can be informed by the ontological criterion of personal persistence, which (...) aims at determining what it takes for an individual to persist from one time to another.

Nearly all large policy decisions influence not only the quality of life for existing individuals but also the number-and even identities-of yet-to-exist individuals. Accounting for these effects in a policy evaluation framework requires taking difficult stances on concepts such as the value of existence. These issues are at the heart of a literature that sits between welfare economics and philosophical population ethics. Despite the inherent challenges of these questions, this literature has produced theoretical insights and subsequent progress on (...) variable-population welfare criteria. A surprisingly bounded set of coherent alternatives exists for practitioners once a set of uncontroversial axioms is adopted from the better-studied welfare criteria for cases where populations are assumed to be fixed. Although consensus has not yet been reached among these remaining alternatives, their recommendations often agree. The space has been sufficiently restricted and well explored that applications of the theoretical insights are possible and underway in earnest. (shrink)

Several areas of welfare economics seek to evaluate states of affairs as a function of interpersonally comparable individual utilities. The aim is to map each state of affairs onto a vector of individual utilities, and then to produce an ordering of these vectors that can be represented by a mathematical function assigning a real number to each. When this approach is used in intertemporal contexts, a central theoretical question concerns the evaluative weight to be applied to utility coming (...) at different times. This question concerns the rate of pure time preference, which is one key determinant of the social discount rate. This article argues that the standard philosophical account of pure time preference is mistaken, because it ascribes to economists a methodological commitment they need not, and often do not, accept. This in turn undercuts the most common philosophical objection to pure time preference, which traces at least to Rawls’s A Theory of Justice. The article then evaluates three further objections to pure time preference, concluding that it might still be defensible under certain circumstances. The article closes by articulating a final argument that is suggested by the “Social, Economic and Ethical Concepts and Methods” chapter of the most recent Intergovernmental Panel on Climate Change report. If this further argument is sound, it would constitute a decisive objection to pure time preference as it currently figures in much intertemporal welfare economics. (shrink)

Behavioural welfare economics has lately been challenged on account of its use of the satisfaction of true preferences as a normative criterion. The critique contests what is taken to be an implicit assumption in the literature, namely that true preferences are context-independent. This assumption is considered not only unjustified in the behavioural welfare economics literature but unjustifiable – true preferences are argued to be, at least sometimes, context-dependent. This article explores the implications of this ‘critique of (...) the inner rational agent’. I argue that the critique does not support a wholesale shift away from the use of true preferences as an evaluative standard in normative economics; instead, the critique implies that behavioural welfare economists need to inquire into and establish the ‘source’ of particular context-dependent choices in individuals’ decision-making. The source determines the permissibility of correcting individuals’ context-dependent choices and can, in some situations, support decisive welfare judgements. (shrink)

This is a fully revised and updated version of Hans van der Doel"s Democracy and Welfare Economics.

This is the first book in welfare economics to be primarily intended for undergraduates and non-specialists. Concepts such as Pareto optimality in a market economy, the compensation criterion, and the social welfare function are explored in detail. Market failures are analysed by using different ways of measuring welfare changes. The book also examines public choice, and the issues of provision of public goods, median voter equilibrium, government failures, efficient and optimal taxation, and intergenerational equity. The three (...) final chapters are devoted to applied welfare economics: methods for revealing people's preferences, cost-benefit analysis, and project evaluation in a risky world. The book is intended for introductory and intermediate courses in welfare economics, microeconomics, and public economics. It will also be suitable for courses in health economics, environmental economics, and cost-benefit analysis, as well as those undertaking project evaluations in government agencies and private firms.

There is growing concern that decision-making informed by machine learning (ML) algorithms may unfairly discriminate based on personal demographic attributes, such as race and gender. Scholars have responded by introducing numerous mathematical definitions of fairness to test the algorithm, many of which are in conflict with one another. However, these reductionist representations of fairness often bear little resemblance to real-life fairness considerations, which in practice are highly contextual. Moreover, fairness metrics tend to be implemented in narrow and targeted toolkits that (...) are difficult to integrate into an algorithm’s broader ethical assessment. In this paper, we derive lessons from ethical philosophy and welfare economics as they relate to the contextual factors relevant for fairness. In particular we highlight the debate around acceptability of particular inequalities and the inextricable links between fairness, welfare and autonomy. We propose Key Ethics Indicators (KEIs) as a way towards providing a more holistic understanding of whether or not an algorithm is aligned to the decision-maker’s ethical values. (shrink)

Contemporary Austrian‐school economists reject neoclassical welfare theory for being founded on the benchmark of a perfectly competitive general equilibrium, and instead favor a formal theory deemed consistent with the notions of radical subjectivism and disequilibrium analysis. Roy Cordato advances a bold free‐market benchmark by which to formally assess social welfare, economic efficiency, and externalities issues. Like all formalist, a priori theory, however, Cordato's reformulation cannot meet its own standards, being theoretically and empirically flawed, and perhaps ideologically suspect.

Normative welfare economics commonly assumes that individuals’ preferences can be reliably inferred from their choices and relies on preference satisfaction as the normative standard for welfare. In recent years, several authors have criticized welfare economists’ reliance on preference satisfaction as the normative standard for welfare and have advocated grounding normative welfare economics on opportunities rather than preferences. In this paper, I argue that although preference-based approaches to normative welfare economics face significant (...) conceptual and practical challenges, opportunity-based approaches fail to provide a more reliable and informative foundation for normative welfare economics than preference-based approaches. I then identify and rebut various influential calls to ground normative welfare economics on opportunities rather than preferences to support my qualified defence of preference-based approaches.

Given the endowment effect, the role of attention in decision-making, and the framing effect, most behavioral economists agree that it would be a mistake to accept the satisfaction of revealed preferences as the normative criterion of choice. Some have suggested that what makes agents better off is not the satisfaction of revealed preferences, but ‘true’ preferences, which may not always be observed through choice. While such preferences may appear to be an improvement over revealed preferences, some philosophers of economics (...) have argued that they face insurmountable epistemological, normative, and methodological challenges. This article introduces a new kind of true preference – values-based preferences – that blunts these challenges. Agents express values-based preferences when they choose in a manner that is compatible with a consumption plan grounded in a value commitment that is normative, affective, and stable for the agent who has one. Agents who choose according to their plans are resolute choosers. My claim is that while values-based preferences do not apply to every choice situation, this kind of preference provides a rigorous way for thinking about classic choice situations that have long interested behavioral economists and philosophers of economics, such as ‘Joe-in-the-cafeteria.’.

Neoclassical economics assumes that individuals have stable and context-independent preferences, and uses preference satisfaction as a normative criterion. By calling this assumption into question, behavioural findings cause fundamental problems for normative economics. A common response to these problems is to treat deviations from conventional rational choice theory as mistakes, and to try to reconstruct the preferences that individuals would have acted on, had they reasoned correctly. We argue that this preference purification approach implicitly uses a dualistic model of (...) the human being, in which an inner rational agent is trapped in an outer psychological shell. This model is psychologically and philosophically problematic. (shrink)

ABSTRACT This paper compares two alternative answers to the question ?Who is the addressee of welfare economics?? These answers correspond with different understandings of the status of the normative conclusions of welfare economics and have different implications for how welfare economics should be adapted in the light of the findings of behavioural economics. The conventional welfarist answer is that welfare economics is addressed to a ?social planner?, whose objective is to maximize (...) the overall well-being of society; the planner is imagined as a benevolent despot, receptive to the economist's advice. The alternative contractarian answer is that welfare economics is addressed to individuals who are seeking mutually beneficial agreements; a contractarian recommendation has the form ?It is in the interests of each of you separately that all of you together agree to do x?. Each of these answers should be understood as a literary convention that uses a highly simplified model of politics. I defend the contractarian approach and show that it is less supportive of ?soft paternalism? than is the welfarist approach. (shrink)

Abstract: This paper examines Mark Blaug's position on the normative character of Paretian welfare economics: in general, and specifically with respect to his debate with Pieter Hennipman over this question during the 1990s. The paper also clarifies some of the confusions that emerged within the context of this debate, and closes by providing some additional arguments supporting Blaug's position that he himself did not provide.

This book presents an exploration of the idea of the common or social good, extended so that alternatives with different populations can be ranked. The approach is, in the main, welfarist, basing rankings on the well-being, broadly conceived, of those who are alive. The axiomatic method is employed, and topics investigated include: the measurement of individual well-being, social attitudes toward inequality of well-being, the main classes of population principles, principles that provide incomplete rankings, principles that rank uncertain alternatives, best choices (...) from feasible sets, and applications. The chapters are divided, with mathematical arguments confined to the second part. The first part is intended to make the arguments accessible to a more general readership. Although the book can be read as a defense of the critical-level generalized-utilitarian class of principles, comprehensive examinations of other classes are included. (shrink)
